NITED STATES SPECIFICATION forming part of Letters 'Application filed January 11, 1886.

To all whom it may concern: I

Be it. known that I, JOHN T. WILsoN, re-

siding at Pittsburg, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Automatic Link andHook Oar-Couplers, of which improvements the following is a specification.

In the aceompanying drawings, which make part of this speciiication, Figure 1 is a sectional elevation of a pair of my improved carcouplers, showing the position of the parts in readiness for coupling when using one of the permanent links. Fig. 2 is a similar View showing the position of the arts.afte; coupling has been effeeted. Fig. 3 is a similar view showing the manner of using a loose link. F'g. t is a top plan View of the couplers.

The invention herein relates to certain improvements in tha-t class or kind of car-coup lers in which the draw-head is provided with a link permane tly connected thereto, and is also so constructed as to permit of the use of a loose or independent link; and the invention has for its object such a construction of the parts of the draw-head that coupling may be effected automatically when cars provided therewith are pushed together, thereby avoid` ing the necessity of the links being guided during the coupling operation, and this automatic action will be elfeeted not only when the permanent link is employed, but also during the use of a loose or independent link.

The Construction of the draw-bars l is the same as in those now in use, except in some particulars hereinafter described. On the lower side or Wall of the drawliar and near its front end are formed lugs or'projeetions 2, (shown in dotted lines in the various views,) between which is pivoted the lower end of what may be termed the stationary pin 3, although said pin is so connected to the drawhead as to have a Slight lateral play. This pin projects up through a slot, 4, in the npper wall of the draw-bar, of a length a little greater than the width of the pin, and to the upper end of the pin 3 is pivoted the real' end of the swinging hook or pin 5. This hook or pin is curved, as shown, on its outer and inner edges, and swiugs down into the drawhead through the slot 6, forned in the upper cne-ooupune.

Serial No. 188.197. (No model.)

normal position thereof, resting upon the projeetion 7, formed in the mouth of the drawhead, as shown.

At the front end of the draw-bar the lower side is made to enrve downwardly, tlus forming an inclined curved surface from the projection 7, to guide a link into proper position for coupling. Between the projection 7 and the pin 3 is formed a recess, 8, for the reception of the forward end of the permanent link 9, which, when not in use, rests upon the lower side of the draw-bar, entirely out of the way of the other parts. This permanent link is put in place before the pin 3 is secured between the lugs 2, and cannot be removed without first removing said pin.

On the rear edge of the pin 3, near its lower end, is formed a hook, 10, for supporting the rear end of the permanent link when in use, and preventing any rearward movement of the link during the coupling operation.

Along the front edge of the pin 3 is forned a series of hooks, 11, adzpted to support the rear end of a loose or independent link during the couplingoperation; such hooks per- 'mitting of any desired inelination of the link. The pin 3 also serves to prevent any rearward movement of the loose link.

The forward ends of the slots 4 and 6 are so located that when a strain is brought upon either the pin 3 or hook 5 both pin and hook will find a firm hearing against the forward ends of said Slots, as is clearly shown in the drawings; and in the portion of the draw-head between the slots 4 and (i is formed a knob or projection, 1.2, adapted to bear on the inner edge of the swinging hook 5. As a result of this Construction, the hook 5 will be slightly raised when the hook is forced backward by the link during the coupling operation.

I claim herein as my invention- In a car-coupler, the comhination of a pin pivoted in the lrawhead, alink pernanently engaged by said pin, and a swinging hook pivoted to the permanent pin and adapted to engage the link ol" an adjacent car, substantially as set for-th.

In testimony wlereof I have hereunto set my hand.
